NHTSA Complaint #11591284 — 2020 HONDA PILOT

While stopped at a red traffic light after taking a freeway exit with one foot on the brake, my 2020 Honda Pilot engaged in auto stop (auto idle stop). When the traffic light turned green, I took my foot off of the brake, the vehicle attempted to start but stalled with the electrical components still on (dashboard indicators and ventilation still on). I stepped on the brake and attempted to put the vehicle in park, but noticed the vehicle would not shift out of neutral. I pressed the start/stop button (ignition) and the dashboard indicators flashed but the engine did not start until the second attempt. Somewhere in between, I pressed the emergency lights to indicate to drivers behind me of an issue. About 15-20 seconds had lapsed during my troubleshooting attempt. Prior to this event, there were at least 8 individual events where when the auto start/stop was engaged and disengaged, the dashboard would flash warning signals for a fraction of a second with an audible warning sound. Dashboard warnings flashed on and off too quickly to clearly see what was being displayed. A short delay in restarting the vehicle from idle stop would occur, about 1-2 seconds but the car would then proceed and run as usual.
